This is the osseous channel formed where the tympanic annulus joins the notched inferolateral aspect of the squamous temporal bone. It is continuous with a cartilaginous channel in the pinna. This combined passageway conducts sound waves to the tympanic membrane.
External comes from the Latin externus meaning outward. Acoustic comes from the Greek word akouein meaning to hear. Meatus literally translates as "a going" from the Latin verb meare meaning to go or pass. The noun form meatus designates a passage.
